The rear portion of the upper is connected to the front portion by tightening and closure elements, whereas the shell base includes two lateral wings extending upwardly, to which a linkage is connected, linking them to the rear portion of the upper where a traction element of the linkage is located. ## Claims ### Claim 1 A ski boot comprising a sole, an opening, and a shell base having a heel portion and an overlying upper, the upper comprising a front portion and a rear portion journalled with respect to said shell base about a transverse journal axis on said heel portion to enable pivoting of said rear portion of the upper towards the rear at the opening of the boot, wherein the rear portion of the upper is connected to the front portion by tightening and closure means, said tightening and closure means being connected between said front portion and said rear portion, two lateral wings integrally connected to said shell base and extending upwardly; linkage means connecting respective said lateral wings to the rear portion of the upper; a traction element for connection to said linkage means being located at the rear portion of the upper, whereby said linkage means and traction element allow said rear portion to freely pivot in a direction from the rear to the front of said boot. ### Claim 2 (depends on 1) A ski boot as defined by claim 1, said upper including an axis, wherein the lateral wings extend upwardly substantially along the axis of the upper. ### Claim 3 (depends on 2) A ski boot as defined by claim 2, wherein the rear portion of the upper at least partially covers the lateral wings. ### Claim 4 (depends on 1) A ski boot as defined by claim 1, wherein the linkage means are connected on each of the lateral wings by at least one anchoring point located between the upper end of each of the lateral wings and the shell base zone corresponding to the malleoli of the skier. ### Claim 5 (depends on 4) A ski boot as defined by claim 4, wherein the linkage means cross a path substantially parallel to a plane of the sole along the rear periphery of the upper and are connected to the traction element by means of return elements. ### Claim 6 (depends on 1) A ski boot as defined by claim 1, wherein the lateral wings of the shell base are deformable transversely to the longitudinal axis of the boot, whereby said wings are more rigid along a direction parallel to said longitudinal axis of the boot than in a direction transverse to the longitudinal axis of said boot. ### Claim 7 (depends on 6) A ski boot as defined by claim 6, wherein the lateral wings comprises a plurality of anchoring points located in the upper portion of the lateral wings along a direction substantially parallel to a plane of the sole. ### Claim 8 (depends on 1) A ski boot as defined by claim 1, wherein the journalled upper portion comprises on each of its sides, a guide opening for passage of the linkage means towards the outside of the boot. ### Claim 9 (depends on 8) A ski boot as defined by claim 8, wherein the guide openings are located, in the upper zone of the journalled upper portion, substantially in the same plane as return elements of the linkage means located at the rear of said upper portion, and wherein a plurality succession of anchoring points are located on the lateral wings of the shell base. ### Claim 10 (depends on 1) A ski boot as defined by claim 1, wherein the traction element comprises a tensioning lever journalled on the rear of the journalled upper portion, said tensioning lever pivoting downwardly. ### Claim 11 (depends on 1) A ski boot as defined by claim 1, said front portion including a front cuff, wherein the journalled upper portion is a collar having lateral flaps for front covering of the front cuff, said front cuff being elastically deformable in a tibial support zone. ### Claim 12 (depends on 11) A ski boot as defined by claim 11, said front portion including front covering tongues, wherein the front covering tongues are provided with closure means having loops. ### Claim 13 (depends on 1) A ski boot as defined by claim 1, said front portion including a front cuff, wherein the journalled upper portion is a rear spoiler that partially covers the lateral wings, whereas the front cuff comprises two rear extensions covering both of the lateral wings as well as an edge of the lateral walls of said rear spoiler, loop closure means for closing the upper. ### Claim 14 (depends on 1) A ski boot as defined by claim 1, wherein the transverse journal axis of the journalled portion of the upper is located in the upper heel zone of the shell base. ### Claim 15 (depends on 14) A ski boot as defined by claim 14, wherein the traction element comprises attachment means for the linkage means, said attachment means being adjustable. ### Claim 16 (depends on 8) A ski boot as defined in claim 8, wherein said linkage means is a cable.
